Solution Overview

Problem

Dynamically changing anchor points in wireless communication systems is challenging due to the variability of optimal anchor points based on user equipment usage, making it difficult to consistently select the most suitable anchor point.

Innovation Solution

An anchor point control device and method that acquires user information, including attributes and states, to select the most suitable anchor point from multiple options for handover operations, and notifies the user device of the selected anchor point, allowing for dynamic adjustment based on mobility and traffic patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If anchor point is dynamically changed based on various conditions, then communication efficiency is improved, but it becomes difficult to consistently select the optimal anchor point

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidanchor point selection accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the network device continuously monitors user equipment information including mobility state, service type, and QoS requirements. This feedback loop enables the system to adaptively select anchor points based on real-time conditions, ensuring both communication efficiency and selection accuracy by constantly adjusting to changing parameters.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes multiple parameters simultaneously including mobility state (stationary, slow-moving, fast-moving), service type (voice, data, video), and QoS requirements to determine the optimal anchor point. By considering changes in these parameters together, the system resolves the contradiction between dynamic adaptation and consistent optimal selection.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If multiple factors are considered for anchor point selection, then selection accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveanchor point selection accuracyVSAvoidselection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the anchor point selection process into distinct evaluation dimensions: mobility state assessment, service type identification, QoS requirement analysis, and anchor point matching. Each segment handles a specific aspect independently, which improves selection accuracy through comprehensive evaluation while managing complexity by organizing the decision process into modular, manageable segments.

Inventive Principle:
Principle #1Segmentation

AI summary

Provided are an anchor point control device and an anchor point control method that make it possible to select a more suitable anchor point when dynamically changing an anchor point (route switching point) . An ME (300) acquires user information indicating at least either an attribute or a state of UE (100), and selects an anchor point out of an anchor point AL and an anchor point AC based on the acquired user information. In addition, the ME (300) notifies the UE 100 of the selected anchor point.
